Presented herein are techniques for invoking user interfaces in graphical
computing environments involving "hooking" gestures applicable to an edge
of a display. These gestures involve positioning a pointer near an edge
of the display depicting the environment, and then moving the cursor to a
second location that is distanced from but near the first location (e.g.,
moving the pointer into a corner of the display, and then toward the
center of the display, or to a midpoint of an adjacent edge of the
display), resulting in the presentation of the user interface under the
pointer at the second location. Variations include presenting a preview
of the user interface (e.g., a subset of a user interface menu) at the
second location while the pointer is in the first location, and
refraining from presenting the user interface upon failing to complete
the gesture or receiving extraneous input before completing the gesture.

The present application is a continuation of U.S. patent application Ser.
No. 13/345,383, filed on Jan. 6, 2012 and also entitled "Edge-Based
Hooking Gestures for Invoking User Interfaces," the entirety of which is
incorporated by reference as if fully rewritten herein.

Description

BACKGROUND

Within the field of computing, many scenarios involve the presentation of user interfaces within a graphical computing environment, such as windows, icons, menu bars, toolbars, and widgets, as well as a background region, such as a desktop
presented as a backdrop for the graphical computing environment. In particular, such user interfaces may present various types of visual controls for interacting with the graphical computing environment, such as adjustable properties of the environment,
adjustable settings of respective applications, and properties of regions associated with the applications (e.g., opening, closing, and repositioning windows for respective applications). A user may manipulate a pointing device (e.g., a mouse,
trackball, touchpad, drawing tablet, stylus, or touchscreen device) to manipulate a pointer within the graphical environment in order to interact with the user interfaces presented therein.

SUMMARY

This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key factors or essential features of the claimed subject
matter, nor is it intended to be used to limit the scope of the claimed subject matter.

Although the presentation of visual controls within the graphical computing environment may enable various operations for respective applications or the environment, such presentation may consume valuable space on the display of the device. In
some scenarios, such consumption may be regarded as an inefficient use of display space that diminishes the amount of display space usable by the application. For example, settings may be accessible through interaction with a visual control such as a
button or menu, but such settings may be infrequently or rarely accessed by the user, and it may not be desirable to present such visual controls in a continuous manner that reduces the size of the display used to present other aspects of the graphical
computing environment, such as the output of the applications. Moreover, such visual controls are often presented in a large non-interactive display element, such as a menu bar displayed along the entire top width of the region where only a small
portion of the menu bar is used to display a small set of options. Therefore, it may be desirable to reduce the amount of "chrome" (e.g., attached visual controls and embedding visual elements) presented within the graphical computing environment in
order to maximize the area of display space that is available for other uses. However, it is still desirable to enable the user to access the operations for which the visual elements may have been presented.

Presented herein are techniques for enabling users to invoke a presentation of a user interface within a graphical computing environment through the detection of gestures performed with the pointer. Such techniques may particularly useful when
implemented in a "chromeless" manner, e.g., where the graphical computing environment refrains from indicating the availability of the user interface before the start of the performance of the gesture. These techniques involve detecting a positioning of
the pointer at a first location near an edge of the display, followed by a movement of the pointer toward a second location that is located near, but at a distance from, the first location (e.g., the first location comprising a corner of the display
adjoining two edges, and the second location comprising a midpoint of one of the edges). This gesture may invoke a presentation of a user interface region of the user interface, such that the user interface region that is positioned near the first
location, but that does not include the first location, such that the user interface does not occlude other visual controls that may be positioned at the first location (e.g., other visual controls positioned in the corner of the display). Additionally,
upon detecting a "hovering" of the pointer at the first location, the device may present a preview of the user interface at the second location, thus encouraging the user to move the pointer toward the second location where the full user interface is
presented.

The configuration of the device to detect such gestures as requests to invoke the user interface may present several advantages. As a first example, the edges of a display, and even more so the corners of the display, are often easily
accessible to a user (according to some consequences of Fitts' Law), and a user may rapidly invoke such gestures, and possibly without regard to the current position of the pointer and even without looking at the display. As a second example, such
gestures are not currently associated with any known functionality, and users may be easily and intuitively trained to utilize such gestures to invoke the user interface. As a third example, such gestures may be detectable with high accuracy, a low
degree of ambiguity, and a comparatively simple analytic process (as contrasted with gestures that involve complex shape analysis, such as the drawing of symbols such as letters). These and other advantages may be achievable through the implementation
of the techniques presented herein.

To the accomplishment of the foregoing and related ends, the following description and annexed drawings set forth certain illustrative aspects and implementations. These are indicative of but a few of the various ways in which one or more
aspects may be employed. Other aspects, advantages, and novel features of the disclosure will become apparent from the following detailed description when considered in conjunction with the annexed drawings.

DETAILED DESCRIPTION

A. Introduction

The claimed subject matter is now described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are
set forth in order to provide a thorough understanding of the claimed subject matter. It may be evident, however, that the claimed subject matter may be practiced without these specific details. In other instances, structures and devices are shown in
block diagram form in order to facilitate describing the claimed subject matter.

Within the field of computing, many scenarios involve a graphical computing environment comprising various user interfaces, such as windows, menu bars, toolbars, notification dialogs, icons representing applications or documents, and widgets
embedded in a desktop. Such graphical computing environments may be generated on a device, e.g., by first rendering a background color or background image; by rendering one or more user interfaces for each application executing on the device; and by
presenting the rendering on a display component of the device, such as a monitor. Some user interfaces may be associated with an application executing on the device, and may be configured to present visual output from the application and/or convey input
through the user interface to the application. Such applications may include user applications, renderings of media objects, configuration dialogs, games, operating system applications (e.g., a file explorer), and graphical interfaces for background
service (e.g., a notification icon stored in a notification icon area).

A user may be permitted to interact with the user interfaces presented in the graphical computing environment. As one such example, the device may comprise a pointing device, such as a mouse, a trackball, a trackpad, a drawing tablet, a
touchscreen, a stylus, a targeting element such as an infrared emitter, and/or a camera configured to detect a manual pointing gesture of a user at the display component. These pointing devices may be used to control a pointer presented on the display
(e.g., represented by a cursor such as an arrow), and the user may utilize the pointer to select, activate, and interact with various user interfaces; e.g., the user may slide a mouse on a flat surface to achieve corresponding movement of the pointer,
may position the pointer over a user interface of interest, and may click a button on the mouse to indicate a selection of the user interface. The device may be configured to support many such operations through the pointing device (e.g., clicking with
one or more particular buttons, double-clicking, dragging an item such as an icon, or creating a marquee or "lasso" to select an area or items of interest). The device may also evaluate the input of the pointing device to identify gestures performed
with the pointer (e.g., a "shaking" of the cursor) and/or of the pointing device (e.g., a single- or multi-touch gesture performed on a touchpad that is to be processed in lieu of corresponding movements on the touchpad). Such manipulations may enable
the execution of many types of activities, including selecting and/or unselecting items; invoking, switching to, or terminating particular applications; and zooming into or out of a portion of the graphical computing environment.

In addition to operations invoked solely through the input of the pointing device, pointer-based user interfaces are frequently used in conjunction with various types of visual controls embedded in the user interface, such as depressable
buttons, selectable radio buttons, checkboxes, sliders, lists, numeric up/down controls, menus and pickers. For example, a window of an application is often presented with a visual frame; a set of buttons at a top corner of the window for frequently
invoked window management functions, such as maximizing, restoring, minimizing, and closing an application; and a top menu bar providing a set of invokable operations exposed by the application. These controls may be applied by default to the window by
the graphical computing environment, or may be specified by the application associated with the window, and may be positioned in an independent, floating, detachable, dockable, and/or attached manner with respect to the window. Some familiar examples
involve techniques for achieving a repositioning of a window on the display. Such repositioning may involve, e.g., altering the location of a window on the display; resizing the window; switching the window to a particular view mode (e.g., a maximized,
fullscreen, windowed, or hidden view mode); and moving the window to a different display (e.g., from a first monitor to a second monitor connected to the same device; from a first virtual display space to a second virtual display space of the same
device; or to a display component of a different device). Because windows are frequently repositioned in window-based graphical computing environments, such devices often provide several ways to invoke the repositioning of a window. For example, the
maximize, restore, and minimize buttons attached to a window enable the repositioning of the window at predefined sizes and locations; the graphical frame of a window enables a user to position the pointer over an edge of the window and drag to adjust
the size of the window; and menu options in a standard application menu enabling the maximizing, restoring, and minimizing of the region. Additional input options may be included to reposition the window without the use of a visual repositioning
control; e.g., keyboard shortcuts may be provided to invoke the maximize, restore, and minimize commands, and a "throw" pointer gesture may be implemented to enable a user to "grab" a window with the pointer and rapidly move the pointer to a particular
location of the display in order to "throw" it into that location.

FIG. 1 presents an illustration of an exemplary scenario 100 featuring a device 102 having a display 104 (e.g., a liquid crystal display (LCD) monitor) whereupon is presented a graphical computing environment 106 within which applications 108
may be executed, and may render output through a window 110 of the graphical computing environment 106. In order to interact with the graphical computing environment 106, a user 112 may manipulate a pointing device 114, such as a mouse, to control a
pointer 116 positioned at a location within the graphical computing environment 106. For example, the user 112 may position the pointer 116 over a visual control 118 within the window 110, such as a button positioned at the top-left corner of the window
110 providing access to general window-management functions, and a menu bar presenting menus of application-specific operations. While the window 110 is activated (e.g., while the pointer 116 is positioned over the window 110, or while the window 110 is
selected as an input focus), input received from the user 112 may be directed to the application 108 associated with the window 110. For example, clicking on the button may result in the presentation of a first user interface 120 (e.g., a pop-out menu
presenting a selectable list of window management operations). Additional visual controls 118 may be presented by the graphical computing environment 106, such as an application launcher that, upon activation with the pointer 116, presents a second user
interface 120 comprising a list of invokable applications, and a settings button that, upon activation with the pointer 116, presents a third user interface 120 comprising a list of operations applicable to the graphical computing environment 106 (e.g.,
displaying settings within the graphical computing environment 106, logging out of a user account, and shutting down the graphical computing environment 106). In this manner, visual elements 118 may be presented within the graphical computing
environment 106 to enable access to various user interfaces 120 associated with applications 108 and the graphical computing environment 106.

However, the implementation of visual controls 118 for respective windows 110 may consume space within the graphical computing environment 106. For example, in the exemplary scenario 100 of FIG. 1, a significant amount of the display space is
consumed by visual controls 118 such as the top menu bar, the application launcher button, the options button, and the visual controls 118 embedded in the window 110. Moreover, some of these elements are embedded in non-interactive visual elements in
order to provide visual alignment and/or consistency among windows 110; e.g., a menu bar may span the entire width of a window 110 but may be only partially utilized by embedded visual controls 118, and the remainder may present non-interactive and
unhelpful visual elements within the graphical computing environment 106. Moreover, the functionality provided by a visual control 118 may be redundant with other visual controls 118; may be invoked only occasionally or rarely, despite the ubiquitous
presentation of the visual control 118; and may be handled entirely by the logic of the application 108 (e.g., the application 108 may present an option within the window 110 to exit the application at an appropriate time, thereby rendering a "close"
button irrelevant and confusing).

These and other considerations may encourage a reduction in the amount of redundant, infrequently invoked, and/or non-functional visual elements ("chrome") within a graphical computing environment 106. However, users 112 may nevertheless wish
to invoke the functionality provided by the omitted visual controls 118. Therefore, it may be desirable to design the graphical computing environment 106 to provide such functionality other than through the use of "chrome." One such technique is the
implementation of "gestures," whereby a particular motion of the pointer 116 may be associated with a particular functionality, such as the "marquee" or "lasso" gesture whereby the drawing of a rectangle enclosing a set of items in a list results in a
selection of the enclosed items, or double-clicking a button on a pointing device to activate an item indicated by the pointer 116. Moreover, it may be desirable to devise gestures that may be distinctively entered by the user 112; that may be
efficiently and accurately distinguished by computational analysis from other gestures and other forms of input); and that are intuitively associated with the invoked functionality (e.g., a recognizable multi-touch gesture may involve a spreading or
pinching of two locations may be intuitively associated, respectively, with a zoom-in operation or a zoom-out operation). The configuration of the device 102 to recognize a distinctive set of gestures, each enabling access to frequently invoked
functionality in an unambiguous manner, may enable a considerable reallocation of the display space of the graphical computing environment 106 from "chrome" to the output of applications 108.

B. Presented Techniques

Presented herein are techniques for facilitating the invocation of a user interface 120 through gestures that are not presently associated with other functionality, that are readily distinguished from other gestures and forms of input, and that
are intuitively associated with the associated functionality of invoking a user interface 120. In particular, it may be desirable to devise a gesture that is associated with a location near an edge of a display 104 of the device 102, which, according to
Fitts' Law, is readily accessible to users 112. However, due to this advantageous accessibility, many graphical computing environments 106 may position the user interface 120 near an edge of the display 104, and/or may implement gestures or other forms
of input with respect to an edge. These alternate uses of the edge of a display 104 may cause two undesirable consequences: first, the gesture may already be associated with other forms of input that are associated with the same edge; second, presenting
the user interface 120 at the first location where the gesture begins may result in an overlapping of other visual elements that are also presented near the same edge. Moreover, it may be further desirable to present the invoked user interface 120 near
the edge only after the gesture is completed, because presenting the user interface 120 near the first location before the gesture is completed may result in an overlapping of other visual elements near the edge even if the user 112 did not intend to
invoke the user interface 120.

For at least these reasons, it may be desirable to devise gestures that conclude at a second location that is near but distanced from the first location where the gesture is initiated, where the movement of the pointer 116 from the first
location to the second location may unambiguously identify a request to invoke the user interface 120. As an additional option, while the invoked user interface 120 may be presented only after the gesture is completed, the graphical computing
environment 118 may present a preview of the user interface 120 at the second location. This preview presentation may both suggest the availability of the user interface 120 to the user 112 when the gesture is commenced and may prompt the user 112 with
the movement to complete the gesture. Moreover, the presentation at the second location (near but distanced from the first location near the edge of the display 106) may avoid overlapping visual elements presented at the first location, particularly
before the intent of the user 112 to invoke the user interface 120 is unambiguously established through the completion of the gesture.

FIG. 2 presents an illustration of an exemplary scenario (presented as a sequence of time points) including the performance of an exemplary gesture devised to invoke a user interface 120. In this exemplary scenario, at a first time point 200,
within the graphical computing environment 106 presented on a display 104, a gesture may be devised that is associated with a particular edge 202 of the display 104 (e.g., a corner adjoining a horizontal edge and a vertical edge of the display 104). In
particular, the gesture may be associated with a first location 204 that is located near the edge 202 where the gesture is commenced (e.g., a small triangular area of the corner of the display 104), and a second location 206 that is near but distanced
from the first location 204 and where the gesture is completed (e.g., a small square area near a midpoint of the vertical edge associated with the corner). At this first time point 200, the pointer 116 may be positioned at an arbitrary position within
the graphical computing environment 106, but at a second time point 208, the user 112 may move the pointer 116 to enter the area comprising the first location 204, and the device 102 may enter a user interface suggestion mode 210 (e.g., the detection of
input initiating but not yet completing a gesture whereby a user interface 120 may be invoked). At a third time point 212, as optional additional aspects of this exemplary gesture, the graphical computing environment 106 may detect a hovering of the
pointer 116 (for a hover duration 214) at the first location 204, and may therefore present a preview 216 of the user interface 120 at the second location 206. The preview 216 may both suggest the availability of the user interface 120 to the user 112,
and may also indicate to the user 112 the second location 206 where the pointer 116 may be moved to complete the gesture. Moreover, the second location 206 may be selected so that the preview 216, when displayed at the second location 206, does not
overlap visual elements at the first location 204. At a fourth time point 218, a movement 220 of the pointer 116 to the second location 206 may result in a completion of the gesture, result in, at a fifth time point 222, a presentation of the user
interface 120 along the vertical edge of the display 104 where the gesture has been performed. In this manner, the user interface 120 may be conveniently invoked by an unambiguous gesture without reliance on chrome, and by suggesting the availability of
the user interface 120 by presenting a preview that does not occlude other visual elements presented at the first location 204, in accordance with the techniques presented herein.

C. Exemplary Embodiments

FIG. 3 presents a first exemplary embodiment of the techniques presented herein, illustrated as an exemplary method 300 of presenting user interfaces 120 within a graphical computing environment 106. The exemplary method 300 may involve a
device 102 having a processor, a display 104, and a pointing device 114 associated with a pointer 116 presented within the graphical computing environment 106. The exemplary method 300 also involves a set of instructions stored in a memory component of
the device 102 (e.g., a memory circuit, a platter of a hard disk drive, a solid-state storage device, or a magnetic and/or optical disc) that, when executed on the processor of the device, causes the device to apply the techniques presented herein.
Accordingly, the exemplary method 300 begins at 302 and involves executing 304 the instructions on the processor of the device 102. More specifically, the instructions are configured to, upon detecting a positioning of the pointer 116 at a first
location 506 near an edge 202 of the display 104, enter 306 a user interface suggestion mode 210. The instructions are also configured to, upon detecting, while in the user interface suggestion mode 210, a movement 220 of the pointer 116 to a second
location 206 that is near the first location 204 and that is distanced from the first location 204, present 308 the user interface 120 at the second location 206. Having achieved the presentation of the user interface 120 according to the techniques
presented herein, the exemplary method 300 ends at 310.

Still another embodiment involves a computer-readable medium comprising processor-executable instructions configured to apply the techniques presented herein. Such computer-readable media may include, e.g., computer-readable storage media
involving a tangible device, such as a memory semiconductor (e.g., a semiconductor utilizing static random access memory (SRAM), dynamic random access memory (DRAM), and/or synchronous dynamic random access memory (SDRAM) technologies), a platter of a
hard disk drive, a flash memory device, or a magnetic or optical disc (such as a CD-R, DVD-R, or floppy disc), encoding a set of computer-readable instructions that, when executed by a processor of a device, cause the device to implement the techniques
presented herein. Such computer-readable media may also include (as a class of technologies that are distinct from computer-readable storage media) various types of communications media, such as a signal that may be propagated through various physical
phenomena (e.g., an electromagnetic signal, a sound wave signal, or an optical signal) and in various wired scenarios (e.g., via an Ethernet or fiber optic cable) and/or wireless scenarios (e.g., a wireless local area network (WLAN) such as WiFi, a
personal area network (PAN) such as Bluetooth, or a cellular or radio network), and which encodes a set of computer-readable instructions that, when executed by a processor of a device, cause the device to implement the techniques presented herein.

An exemplary computer-readable medium that may be devised in these ways is illustrated in FIG. 4, wherein the implementation 400 comprises a computer-readable medium 402 (e.g., a CD-R, DVD-R, or a platter of a hard disk drive), on which is
encoded computer-readable data 404. This computer-readable data 404 in turn comprises a set of computer instructions 406 configured to operate according to the principles set forth herein. In one such embodiment, the processor-executable instructions
406 may be configured to perform a method of presenting a user interface within a graphical computing environment, such as the exemplary method 300 of FIG. 3. Some embodiments of this computer-readable medium may comprise a nontransitory
computer-readable storage medium (e.g., a hard disk drive, an optical disc, or a flash memory device) that is configured to store processor-executable instructions configured in this manner. Many such computer-readable media may be devised by those of
ordinary skill in the art that are configured to operate in accordance with the techniques presented herein.

D. Variations

The techniques discussed herein may be devised with variations in many aspects, and some variations may present additional advantages and/or reduce disadvantages with respect to other variations of these and other techniques. Moreover, some
variations may be implemented in combination, and some combinations may feature additional advantages and/or reduced disadvantages through synergistic cooperation. The variations may be incorporated in various embodiments (e.g., the exemplary method 300
of FIG. 3) to confer individual and/or synergistic advantages upon such embodiments.

A first aspect that may vary among embodiments of these techniques relates to the scenarios wherein such techniques may be utilized.

As a first variation of this first aspect, these techniques may be utilized with many types of devices 102, such as servers, workstations, laptop or palmtop computers, tablets, phones, personal data assistants, media players, game consoles, and
appliances.

As a second variation of this first aspect, these techniques may be utilized with many types of displays 104, such as active- or passive-matrix liquid crystal displays (LCD), organic or traditional light-emitting diode (LED) displays,
cathode-ray-tube (CRT) displays, and projectors. Such displays 104 may also exhibit various features, including various physical sizes, aspect ratios, resolutions, pixel densities, adjustable properties, and three-dimensional image simulation. The
device 102 may also have one or multiple displays 104 arranged in various ways (e.g., an aggregate desktop presented seamlessly across the displays 104, a set of distinct and isolated display spaces presented on different displays 104, or a mirrored
desktop that is partially or wholly redundantly presented on several displays 104). Additionally, in some variations, a first device 102 may apply the techniques presented herein for windows 110 presented on a display 104 of a second device 104 (e.g., a
terminal services client presenting on a display 104 the graphical computing environment generated by a terminal server).

As a third variation of this first aspect, these techniques may be utilized with many types of pointing devices 114, such as a mouse, trackball, trackpad, pointing stick, joystick, or drawing tablet. The pointing device 114 may also be
incorporated in the display 104, such as a magnetic or capacitative touch-sensitive display capable of detecting touch by a finger of a user 112 or by a stylus. Other pointing devices 114 may include a camera, and may correlate movements of the pointer
116 with movements of a user (e.g., applying image evaluation techniques to detect the body position and physical gestures of the user 112) or a pointing device, such as an infrared emitter. Such pointing devices 114 may also include various properties
that may affect the pointer 116, such as sensitivity, acceleration, the inclusion of buttons and/or wheels, the detection of various axes of movement (possibly including a third dimensional axis and/or gyroscopic sensors detecting device attitude such as
tilt), and sensitivity to the touch of the user, as in a touch-sensitive mouse. As a further variation, such pointing devices 114 may generally correlate with the pointer 116 in various modes, such as an absolute correlation (e.g., on a touch-sensitive
display 104, the location touched by the user 112 is the location of the point 116; or on a touchpad, the size and dimensions of the touchpad may be scaled to the size and dimensions of the display 104, such that touching a particular location on the
touchpad positions the pointer 116 at the corresponding scaled position on the display 104) and a relative correlation (e.g., input from a mouse or touchpad may be interpreted not as a location of the pointer 116 on the display 104, but as directional
motion of the pointer 116 within the graphical computing environment 106).

As a fourth variation of this first aspect, these techniques may be utilized to invoke many types of user interfaces 120. As a first such example, the user interfaces 120 may be associated with the graphical computing environment 104 and/or one
or more applications 108. As a second such example, the user interfaces 120 may include many types of visual elements 118, such as modal or modeless windows, interactive and non-interactive dialogs, toolbars, menu bars, renderings of media objects such
as documents and images, icons, and widgets embedded in a desktop. Those of ordinary skill in the art may devise many scenarios wherein the techniques presented herein may be utilized.

D2. Gesture Variations

A second aspect that may vary among embodiments of these techniques relates to variations in the gestures detectable by such techniques.

As a first variation of this second aspect, the gestures may be associated with particular edges 202 of a display 104. As a first such example, the first location 204 may comprise a location near a corner of the display 104 adjoining two
selected edges 202 of the display 104, and the second location 206 may comprise a midpoint of a selected edge 202 (or vice versa). As a second such example, the first location 204 may comprise a location near an edge 202 of the display 104, and the
second location 206 may comprise a location between the first location 204 and the center of the display 104.

As a second variation of this second aspect, the gesture may comprise additional forms of input combined with the positioning of the pointer 116 in the first location 204 and the movement 220 of the pointer 116 to the second location 204. As a
first such example, the gesture may involve hovering the pointer 116 at the first location 204 and/or the second location 206. As a second such example, the gesture may involve activating the pointer 116 at the first location 204 and/or the second
location 206 and/or therebetween, e.g., clicking a button of a mouse at the first location 204 and/or the second location 206, or performing a "drag" operation from the first location 204 to the second location 206. As a third such example, the gesture
may also involve other forms of input through other input devices, such as depressing a key on a keyboard while performing the gesture.

As a third variation of this second aspect, the graphical computing environment 106 may visually indicate the availability of the gesture in various ways. As a first such example, the graphical computing environment 106 may present a visual
indicator at the first location 204 of the user interface 120 or the availability of the gesture, such as an interactive or non-interactive target. Alternatively, the graphical computing environment 106 may refrain from presenting visual indicators
(e.g., a "chromeless" implementation of the gesture). As a second such example, between the initiation of the gesture at the first location 204 and the completion of the gesture at the second location 206, the graphical computing environment 106 may
present a visual indication of the second location 206 in order to encourage the completion of the gesture, or may refrain from presenting any such visual indication in order to promote the "chromelessness" of the graphical computing environment 106.

As a particular example of this third variation of this second aspect, and as illustrated in the exemplary scenario of FIG. 2, the visual indication of the second location 206 may comprise a preview 216 of the user interface 120, such as a
portion of the user interface 120 (e.g., a textual or pictorial description of the user interface 120; a subset of visual controls of the user interface 120 that indicate the type of functionality exposed by the user interface 120; a non-interactive
version of the user interface 120, such as a thumbnail or a partially transparent version of the user interface 120; and/or a presentation of the visual controls 118 of the user interface 120 without an isolating background of the user interface 120).
As the movement 220 of the pointer 116 from the first location 204 to the second location 206 is detected, the preview 216 may be replaced with the user interface 120. As a further example, if the user interface 120 comprises a user interface region
extending to the edge 202 of the display 104, the preview 216 may be positioned at the second location 206 such that it does not extend to the edge 202 of the display 104, thereby avoiding an occlusion of any other visual elements that are positioned
near the edge 202 of the display 104. As an additional option, the preview 216 may only be presented after detecting a "hovering" of the pointer 116 within the first location 204, measured as a hover duration 214 from the arrival of the pointer 116 at
the first location 204. This option may inform an inexperienced user 112 of the availability of the user interface 120 and the completion of the associated gesture, while also enabling an experienced user 112 to invoke the user interface 120 without
having to "hover" the pointer 116 at the first location 204 or view the preview 216.

As a fourth variation of this second aspect, the detection of the gesture within the graphical computing environment 106 may be performed in many ways. As a first such example, the graphical computing environment 106 may endeavor to detect an
initiation of the gesture by, while not in the user interface suggestion mode 210, continuously comparing the location of the pointer 106 with the first location 204 of the gesture; and, while in the user interface suggestion mode 210, continuously
evaluating pointer input of the pointer 116 to detect a movement 220 to the second location 206. As a second such example, the graphical computing environment 106 may not continuously monitor the pointer input of the pointer 116, but may include a
trigger that, when activated, indicates input correlated with the gesture. For example, the graphical computing environment 106 may be particularly configured to display a set of regions (e.g., windows 110), and may additionally include a window 110
covering the area of the first location 204 and having no visual appearance. The graphical computing environment 106 may already be generally configured to detect the entry of a pointer 116 into the areas of respective windows 110, and to notify such
windows 110 of such pointer input. The non-visible window 110 positioned at the first location 116 may interpret notification of the entry of the pointer 116 into the area of the window 110 as an initiation of the gesture. Moreover, the non-visible
window 110 may send the pointer input to any visual controls near (e.g., below) the window, in case such pointer input is intended for such underlying visual controls and not as part of the gesture.

As a fifth variation of this second aspect, if the user 112 does not complete an initiated gesture, the graphical computing environment 106 may construe the input as an inadvertent initiation of the gesture and a cancellation of the user
interface suggestion mode 210. As a first such example, upon failing to detect the movement 220 of the pointer 116 to the second location 206 within a gesture completion duration from entering the user interface suggestion mode 210, the graphical
computing environment 106 may cancel the user interface suggestion mode 210. As a second such example, upon detecting input other than the movement 220 of the pointer 116 to the second location 206 while in the user interface suggestion mode 210 (e.g.,
movement of the pointer 116 away from the second location 206, an activation of the pointer 116 such as a depression of a mouse button, or input from another input device such as a keyboard), the graphical computing environment 106 may cancel the user
interface suggestion mode 210.

As a sixth variation of this second aspect, the details of such gestures may be adjusted for execution on a device 102 having two or more displays 104. In many such scenarios, the displays 104 may be logically arranged to reflect a single
logical display. For example, a logical display may comprise a first logical display space and a second logical display space that are logically adjacent, such that moving the pointer 116 past the right edge of the first logical display space causes the
pointer 116 to emerge from the left edge of the second logical display space. The arrangement of the logical display spaces within the logical display may or may not be consistent with the physical arrangement of such displays 104; e.g., while it may be
advantageous to position a first display 104 presenting the first logical display space adjacent to and to the left of a second display 104 presenting the second logical display space, the displays 104 may be located in other physical arrangements, such
as the first display 104 above, below, or to the right of the second display 104. In relation to the techniques presented herein, in multi-display scenarios, an edge 202 of a logical display space may operate not as a hard boundary that resists
overshooting of the pointer 116 past the edge 202, but rather as a portal to a second logical display space, such that even minimal overshooting of the first location 204 causes the pointer 116 to move past the first location 204 and onto a second
logical display space. Accordingly, the edge 202 may be less readily accessible (due to Fitts' Law), and the gesture may be adapted to improve the accessibility of the associated functionality.

As a first example of this sixth variation, the gesture may be adjusted in order to distinguish an initiation of a gesture from a transition between the logical display spaces presented by different displays 104 that happens to pass through the
first location 204. For example, the gesture may be initiated only upon detecting a movement from within the logical display space of a display 104 to a first location 204 within the same logical display space of the same display 104.

As a second example of this sixth variation, in order to adjust for inadvertently overshooting the first location 204 within a first logical display space of a first display 104 that is logically adjacent to a second logical display space of a
second display 104, the first location 204 may be extended into the second logical display space of the second display 104. For example, the first location 204 may be adapted to include an edge region, comprising a first region portion near an edge 202
of the first logical display space of the first display 104, and a second region portion near an adjacent edge 204 of the second logical display space of the second display 104 having a second region portion edge that is adjacent to a first region
portion edge of the first region portion; and the detection of the pointer 116 within either region portion of the edge region may be construed as the positioning of the pointer 116 at the first location 204. This detection, followed by the movement 220
of the pointer 116 to the second location 206, may cause the user interface 120 to appear in the first logical display space of the first display 106.

FIG. 5 presents an illustration of an exemplary scenario (presented as a series of time points) featuring the implementation of the gestures presented herein on a device 102 having two displays 104 configured to share a logical display 502
comprising a first logical display space 504 presented on a first display 104 and a second logical display space 504 presented on a second display 104. At a first time point 500, the first location 204 in which a gesture may be initiated is defined as
an edge region comprising a first region portion 506 positioned near a first edge 202 of the first display 104 and a second region portion 506 positioned on a logically (and, coincidentally but not necessarily, also physically) adjacent edge 202 of the
second display 104, and may be completed by a movement 220 of the pointer 116 to a second location 206 defined only in the first logical display space 504 on the first display 104. At a second time point 508, when the pointer 116 is positioned within
the second region portion 506 of the second display 104, the graphical computing environment 106 may enter a user interface suggestion mode 210 (e.g., at a third time point 510 following a hovering of the pointer 116 in the second region portion 605,
presenting a preview 216 of the user interface 120 at the second location 206 on the first display 104). The completion of the gesture through a movement 220 from either region portion 506 to the second location 206 may result in the presentation of the
user interface 120 on the first display 104.

Additional variations of this second variation of this sixth aspect may be included to account for the inclusion of the second region portion in the edge region. As a first such example, if the presentation of a preview 216 is preceded by a
hovering of the pointer 116 in the first region portion, the hover duration may be different when the pointer 116 is positioned in the second region portion on the second display 104 (e.g., by defining a first hover duration for the first region portion,
and a second hover duration for the second region portion that is different from the first hover duration). As a second such example, if the device 102 is configured to terminate the user interface suggestion 210 if the pointer 116 is not moved from the
first region portion to the second location 206 within a gesture completion duration, this gesture completion duration may be extended if the pointer 116 is positioned within the second region portion (e.g., to account for the further length of the
movement 220 when initiated from a second display 106). Thus, the device 102 may define a first gesture completion duration when the gesture is initiated in the first region portion, and a second gesture completion duration (which is greater than the
first gesture completion duration) when initiated in the second region portion. As a third such example, the completion of this gesture may have various effects within the second logical display space of the second display 104. For example, in addition
to causing the device 104 to present the first user interface 120 at the second location 206 on the first display 104, the gesture may cause the same user interface 120 to be presented at a location on the second display 104; a different user interface
120 to be presented on the second display 104; or no effect with respect to the second display 104. Those of ordinary skill in the art may devise many such variations of the gestures in accordance with the techniques presented herein.
